[Numpy-discussion] sampling arrays

2013-06-16 Thread Sudheer Joseph
Dear experts,    Is it possible to sample a 4D array of numpy at given dimensions with out writing loops? ie a smart python way? for example, I have a  data cube with cube=c(x,y,z,t) dimensions which are essentially latitude longitude depth and time. Is it possible to sample this

Thank you, No if the location ( space time or depth) of choice is not available then the function I was looking for should give an interpolated value at the choice. with best regards, Sudheer - Original Message - From: Henry Gomersall h...@cantab.net To: Discussion

Here is a solution I got. I think I need to do the rest with loop. Though I am seeing an interpnd I could not find a documentation on that or example. http://docs.scipy.org/doc/scipy/reference/generated/scipy.interpolate.RectBivariateSpline.html#scipy.interpolate.RectBivariateSpline Thank you

Hi! I know it is pretty much the same as you did before, but has been useful for me in the past. Instead of saving each array separately, just create a dictionary and save the it, something like d= {put_all_your_arrays_here} savez_compressed('file.npz', **d) -- Camilo Jiménez On Sat, Jun 15,

[Numpy-discussion] bug fixes: which branch?

What is the preferred strategy for handling bug fix PRs? Initial fix on master, and then a separate PR to backport to v1.7.x? Or the reverse? It doesn't look like v1.7.x is being merged into master regularly, so the matplotlib pattern (fix on maintenance, merge maintenance into master) seems
